Three Practical Uses of 3D Printers in the medical Field

In the past, the use of 3D printers was somehow microscopic to creating scale models in engineering and associated fields. You do not indubitably see these printers much in other fields because of their prohibitive costs. However, advancements in this printing technology have industrialized in such a way that there are now 3D printers that cost a lot cheaply than they used to. The price of these machines has located them within the reach of wider audiences.

Included in these audiences are practitioners in the medical field. The availability of 3D printers has come to be invaluable for doctors because these machines help them do their jobs with a higher degree of precision. These machines make them more able to treat their patients and save lives.

How are 3D printers helpful in the medical field? Here are three examples of how they are used in medicine.

Three Practical Uses of 3D Printers in the medical Field

1. Surgery. The use of 3D printing in surgical operation has paved the way for more accuracy in involved operations, with a greater degree of success. For example, if a surgeon needs to remove a tumor from a sick person but there is a huge chance that he or she will hit a nerve or an artery in doing so, the surgeon can generate a 3D model of the tumor from the patient's Ct scans using a 3D printer. The surgeon can then custom on the model before working on the patient. In this way, the surgeon will be able to make the critical incisions with confidence. The inherent harm or side effects of the surgical operation can also be avoided.

2. Facial reconstructive surgery. When a sick person has suffered critical damage to his or her facial features, reconstructive surgeons now make use of 3D printers to generate models out of which the prosthetics or the synthetic skin will be made. What reconstructive surgeons do is to generate a map of the patient's face on special software and using images taken with a 3D camera. From this facial mask, the surgeons will make a mask that will then guide them in conducting the reconstructive surgery.

3. Tissue and organ engineering. Researchers involved in tissue engineering and synthetic organ building have now turned to 3D printers to synthesize entire tissues and organs. Bioengineers do this by creating scaffolds that will sustain the living cells they will generate. The scaffolds are made on machines that work using inkjet technology or fused deposition modeling. According to researchers, 3D printing will make organ transplants easier because organs and tissues can be generated on demand. It can also lessen organ rejection among patients because the living cells used in engineering these organs can be harvested from the patient's body itself.

The use of 3D printers face the fields of engineering may sound like something out of a science fiction story. But life has a way of imitating art, and soon adequate we may be able to use 3D printers at home for even small medical emergencies and first aid.

Laser Printers And Inkjet Printers - Advantages And Disadvantages

When selecting a printer the first option will be either to buy a laser printer or an inkjet printer. The following summarize the main advantages and disadvantages of inkjet and laser printers.

Inkjet Printers

Inkjet Printer Work

Inkjet printers works by propelling droplets of ink onto the paper. The ink is released from small removable cartridges and if it is a colour inkjet printer there will usually be a black cartridge and three dissimilar coloured cartridges. You can either replace the whole cartridge or refill the cartridges with a extra refill kit.

Laser Printers And Inkjet Printers - Advantages And Disadvantages

Advantages

  • Inkjet printers are considerably cheaper to buy.
  • High end printers are capable of producing good ability images when used with extra paper.
  • Most models are relatively light weight and compact so they don't take up too much space on the desk.

Disadvantages

  • Due to the cost of ink, running an inkjet printer over time is a more costly than a laser printer.
  • Prints emerge from the printer slightly wet and may need time to dry.
  • Printing is slower and therefore inkjets aren't designed for high volume printing.

Laser Printers

This printer incorporates a laser beam as a part of the image processing. Rather than using ink a laser printer uses toner, a dry plastic powder combined with carbon black or colouring agents. The consumable a part of the printer is encased in a cartridge which needs to be substituted from time to time.

Advantages

  • Laser prints are commonly very high and very accurate.
  • For high volume printing laser printers are considerably cheaper to run.
  • Printing is fast so they can cope large volumes.
  • Due to the technology used prints from a laser printer emerge from the printer dry to the touch.

Disadvantages

  • Buying a laser printer can be costly when compared to an inkjet.
  • Colour laser printers are significantly more costly than a colour inkjet.
  • Laser printers are larger and heavier as they need to contain the imaging drum and laser technology.
